Email Verifier

Verify the validity of any email address with the most complete email verification service.

Never get bounces anymore.

We designed the Email Verifier to be as complete as possible, with
validations made at multiple levels: format, domain information,
response of the mail servers and comparison with our unique base of
200+ million professional email addresses.

Common questions about the Email Verifier

Does an email address marked "deliverable" have no chance of bouncing?

The verifications are never totally sure, but we can guarantee that
more than 95% of "deliverable" email addresses won't bounce.

What exactly does it mean when an email address is marked "risky"?

When an email address is tagged "risky", it means the server check
seems to work, but we have reason to believe the email may not be
read by anyone.

This can happen in several cases, for example:

The email seems to be received, but the servers also seem to accept
every email address.

The email seems to be received, but it looks like gibberish (for
example "e9v3mc3@company.com").

Does it send an email to do the verification?

The email checker does the validation without sending an email, by
directly connecting to the SMTP server.

Is the Email Verifier free?

When you are logged in, every verification counts as one request. With a
free account, you can
use up to 50 requests/month.
If you need more, you can upgrade to the plan that suits your needs. Please check our
pricing for more information.

What does an "accept all" status mean?

It means the mail server accepts all the email addresses sent on the
domain, whether they have actually been created or not. In this case,
the SMTP verification isn't relevant and we mark the email address
as "risky" unless we have other strong signals indicating that the
email address really exists.

What do you check for when verifying emails?

This is the list of verifications we do:

Valid format: First, we verify the format of the email address is
correct and looks something like "email@provider.com".

Gibberish Email Address: We check to ensure the address doesn't look
like a random email address. For example, 1e49cs1pb6@company.com doesn't
pass the test.

Disposable Email Address: We check if the email address has a domain
name used for temporary email addresses.

Webmail Email Addresses: We verify if the email address uses a webmail
like Gmail or Yahoo.

Presence of MX Records: We check if there are MX records on the
domain. If there aren't, the email address can't receive emails.

Presence of SMTP Server: This check is successful if we are able to
connect to the SMTP server (indicated in MX records).

SMTP Check: We test the email address and see if it bounces or not, whithout
sending an email.

Accept-all Domain: We check if the server has a catch-all policy which
accepts all the email addresses.

Can I verify email addresses in bulk?

Yes, you can upload a list of email addresses and have it verified with
